ICE-PITCHER.

SPECIFICATION forming part of Letters Patent No. 261,199, dated July 1-8, 1882.

Application filed June 20, 1882.

To all whom 'it' may concern Be it known that I, JSTUS BRAUER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Ice-Pitchers 5 and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates-to improvements in icepitchers; and the object is to construct anicepitcher that is a perfect non-conductor of heat, and by which the sweating on the outside caused by condensation is prevented, and at the same time to admit air intothe pitcher whenever water is withdrawn therefrom and assist in giving a proper amount of ventage.

The invention consists in making the pitcher with double walls,top and bottom, as also the spout, and fillingthe space with closely-rammed granulated cork, prepared especially for the purpose and of a nearly uniform size; and it also consists informing an opening or perforation through the top or cover, having a cavity or enlargement near its upper end, in which is placed a ball-valve, which closes the ingress of air through the opening at all times excepting when the pitcher is tilted and water is withdrawn through the spout,- when the ball rolls t-o one side and admits the air, all of which will be more fully described hereinafter, reference being had to the accompanying drawings and the letters of reference marked thereon.

In the accompanyingdrawings,Figurel represents a vertical cross-section of my improved pitcher. Fig. 2 is an enlarged View of the opening and ball-valve.

In the drawings, A and B are the outer and inner walls of an ice-pitcher, with a double bottom, C. The spout D is also made hollow or double, as well as the top or cover E. The upper edge or rim of the pitcher is also made double, and into all the spaces thus formed properly prepared granulated cork of as nearly uniform .size as possible is closely packed or rammed, so as to form a practically solid mass.

' The top or cover E is made to closely fit the pitcher, so as to prevent ingress or egress of air, and the adjoining edges of both the body of the pitcher, as also the top, being lled with the prepared cork, prevent any condensation.

(No modell) .terior of the pitcher, and thus create a vent.

The upper part or knob, a, of the pitcher is made removable and screwed into its place, so as to permit the introduction ot' the ball-valve, as also for the purpose of cleaning the cavity.

I am aware that water-coolers have been made having double walls, top and bottom, be tween which granulated cork and other nonconducting material have been loosely placed, but leaving air-spaces between the pitchers, and not closely rammed, so as to form a practically-solid mass, and I therefore disclaim such; but,

Having thus desclibed my invention, what I claim is l. An ice-pitcher having double walls, top and bottom, the space between which is packed with closely-rammed granulated cork of nearly uniform particles or size, substantially as specified.

2. An ice-pitcher having its top or cover provided with a perforation, d, having acavity, e, in combination with a valve, b, substantially as and for the purpose set forth.

3. An ice-pitcher having its top provided with a removable knob, a, a perforation, d, having an enlarged cavity, e, for the reception of a ball-valve,'b, as and for the purpose specied.

4. An icepitcher having double walls, top and bottom, packed with closely-rammed granulated cork of nearly uniform particles, in combination with the cover having a perforation, d, with cavity e for the valve b, as and for the purpose described.

In testimony whereof I hereto affix my sig- A. T. SANGsToN, LLOYD F. KELEHER.
